Analysis of characteristic motions and their relations in radio gymnastic exercises

Abstract

This paper focuses on the hypothesis that some of elemental motions are classified into several groups which may correspond to cultural, geographical or generational human groups. We propose a method to find characteristic motions which express differences of different human groups. We used a method which describes an activity as a sequence of symbols. The proposed method discovers characteristic patterns by observing relation among frequent sub-sequences in the sequences. We applied the method to radio gymnastic exercises, and discovered characteristic patterns that group the exercisers.
